The code that manages objects of this class is an in-process
handler. This is a DLL that runs in the client process and
implements client-side structures of this class when instances
of the class are accessed remotely.

A 64-bit floating point number representing the number of days
(not seconds) since December 31, 1899. For example,
January 1, 1900, is 2.0, January 2, 1900,
is 3.0, and so on). This is stored in the same representation as
VT_R8.

If the type indicator is combined with
VT_ARRAY by an OR operator, the value is a pointer to a
SAFEARRAY. VT_ARRAY
can use the OR with the following data types: VT_I1,
VT_UI1, VT_I2, VT_UI2,
VT_I4, VT_UI4, VT_INT,
VT_UINT, VT_R4, VT_R8,
VT_BOOL, VT_DECIMAL, VT_ERROR,
VT_CY, VT_DATE, VT_BSTR,
VT_DISPATCH, VT_UNKNOWN and
VT_VARIANT.
